  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: video: check for error while searching for backlight device parent\n\nIf acpi_get_parent() called in acpi_video_dev_register_backlight()\nfails, for example, because acpi_ut_acquire_mutex() fails inside\nacpi_get_parent), this can lead to incorrect (uninitialized)\nacpi_parent handle being passed to acpi_get_pci_dev() for detecting\nthe parent pci device.\n\nCheck acpi_get_parent() result and set parent device only in case of success.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.",
